Prox1 gene plays a critical role in formation and maintenance of lymphatic system

A century after the valves that link the lymphatic and blood systems were first described, St. Jude Children's Research Hospital scientists have detailed how those valves form and identified a gene that is critical to the process.

Potential fish enzyme biomarker for environmental toxins

The level of the enzyme carbonyl reductase (CBR) is elevated in the livers of fish that have been exposed to cleaned wastewater. Scientists at the University of Gothenburg can show that CBR has properties that may make it suitable to be used as a biomarker, an early warning signal of environmental toxins. The aim of the project is to achieve better environmental monitoring.

Research: Nucleolar disruption could destroy cancer cells

DAMAGING a cell's nucleolus could destroy cancer cells by increasing levels of the most important tumour prevention protein, p53, reveals research presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool, today.

Daily intake of Souvenaid improves memory in people with mild AD

A second clinical trial of the medical food Souvenaid confirmed that daily intake of the nutritional intervention improves memory in people with mild Alzheimer's disease.

Exendin-4 drug could prevent later development of diabetes in children

Pediatric researchers who tested newborn animals with an existing human drug used in adults with diabetes report that this drug, when given very early in life, prevents diabetes from developing in adult animals. If this finding can be repeated in humans, it may become a way to prevent at-risk infants from developing type 2 diabetes.

Link between eating nuts and higher levels of serotonin in MetS patients

For the first time, scientists report a link between eating nuts and higher levels of serotonin in the bodies of patients with metabolic syndrome (MetS), who are at high risk for heart disease.

Tufts University introduces MyPlate for Older Adults

Nutrition scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University are introducing today the MyPlate for Older Adults which corresponds with MyPlate, the federal government's new food group symbol.

Knife-edge scanning microscopy rapidly maps new blood vessels in organs

Like normal tissue, tumors thrive on nutrients carried to them by the blood stream. The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too. To better understand the relationship between cancer and the vascular system, researchers would like to make detailed maps of the complete network of blood vessels in organs. Unfortunately, the current mapping process is time-consuming: using conventional methods, mapping a one-centimeter block of tissue can take months.

NPS announces new data from GATTEX Phase 3 study on short bowel syndrome

NPS Pharmaceuticals, Inc., a specialty pharmaceutical company developing innovative therapeutics for rare gastrointestinal and endocrine disorders, today announced new data from STEPS 2, a long-term open-label study, showing that GATTEX (teduglutide) was associated with achieving and maintaining clinically meaningful reductions in parenteral nutrition (PN) and intravenous (IV) fluid volume in adult subjects with short bowel syndrome.

Vampire-like bacteria has potential to serve as living antibiotic

A vampire-like bacteria that leeches onto specific other bacteria - including certain human pathogens - has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates.

ER-positive breast cancer patients with high levels of heat shock factor 1 experience poor outcomes

Whitehead Institute scientists report that patients whose estrogen receptor (ER)-positive breast cancers have high levels of the ancient cellular survival factor heat shock factor 1 (HSF1) experience poor outcomes—including increased mortality.

Limited alcohol consumption can cause gastrointestinal problems

Just one drink per day for women -- two for men -- could lead to small intestinal bacterial overgrowth (SIBO) and subsequently cause gastrointestinal symptoms like bloating, gas, abdominal pain, constipation and diarrhea, according to the results of a new study unveiled today at the American College of Gastroenterology's (ACG) 76th Annual Scientific meeting in Washington, DC.

Fat cells play a major role in mediating ovarian cancer metastasis

A large pad of fat cells that extends from the stomach and covers the intestines provides nutrients that promote the spread and growth of ovarian cancer, reports a research team based at the University of Chicago in the journal Nature Medicine, published online October 30th, 2011.

Study uncovers mTOR's complex signaling pathway

Even yeast understand austerity. A finely tuned system evolved early on to help cells survive in a world where good times come as fast as they go. The system, a molecular switch found in organisms from yeast to humans, involves a nutrient-sensing protein that turns growth on in times of plenty and shuts it off when times are lean.

Insulin resistance paradox

Obesity and insulin resistance are almost inevitably associated with increases in lipid accumulation in the liver, a serious disease that can deteriorate to hepatitis and liver failure. A real paradox in understanding insulin resistance is figuring out why insulin-resistant livers make more fat. Insulin resistance occurs when the body does a poor job of lowering blood sugars.

Super broccoli on the shelves to protect from heart disease

British scientists unveiled a new breed of broccoli that experts say packs heavy on nutritional values. The new broccoli was specially grown to contain two to three times the normal amount of glucoraphanin, a nutrient believed to help ward off heart disease. Glucoraphanin breaks fat down in the body, preventing it from clogging the arteries.

Yo-yo dieting can affect appetite hormones for up to a year

A new study suggests that the ‘yo-yo’ effect that dieters experience of shedding pounds and gaining them back may be due to the persistence of hormones that drive the urge to eat even a year after weight loss.

VitaYeast project to curb global malnutrition

Any way you slice it, bread that contains critical nutrients could help combat severe malnutrition in impoverished regions. That is the goal of a group of Johns Hopkins University undergraduate students who are using synthetic biology to enhance common yeast so that it yields beta carotene, the orange substance that gives carrots their color. When it's eaten, beta-carotene turns into vitamin A.

BPA exposure in mothers may affect unborn daughters’ behavior: Study

A new federal study revealed Monday in the journal Pediatrics shows that bisphenol A (BPA) - a chemical used widely in plastic bottles, metal cans and other consumer products could be linked to behavioral and emotional problems in toddler girls.
